使用DS1825和STM32G431RB简化温度监测

/*!
 * @file main.c
 * @brief Thermo2 Click example
 *
 * # Description
 * This example demonstrates the use of Thermo 2 click board by reading
 * and displaying the temperature in Celsius.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Reads and displays the temperature measured by the click board on the USB UART
 * approximately every 800ms as this matches the required conversion time for 12-bit 
 * temperature resolution.
